About JaScore
About This Project
JaScore is an independent data journalism project that collects, analyzes, and visualizes livability data for major Japanese cities. Our goal is to bridge the information gap between Japan's rich government open data and people who want to understand what it's really like to live in different Japanese cities.
Meet the Characters
On each city page, Alex, Yuki, and Kai discuss what it's really like to live there.
Alex
Foreigner
Western, late 20s. Loves Japan, has visited a few times, and loosely thinking "maybe I'd live there someday." Upbeat and easy-going — asks the casual questions everyone wants to ask.
Yuki
Japanese local
Early 30s, based in Tokyo. Vaguely interested in relocating or trying a remote-work lifestyle. More "that'd be nice someday" than actively planning. Grounded, practical perspective.
Kai
Data Analyst
Tells you what's great about the city, backed by data. Always finds the positive angle — lower scores become 'all about neighborhood choice' or 'flip side is...'. Their thing is 'but here's what's great.'
Methodology
Scores are calculated using min-max normalization across all cities in our dataset. A score of 100 represents the best-performing city for that metric, and 0 represents the lowest. Scores are relative and will shift as more cities are added.
The overall score is a weighted average of five axes (Safety, Cost, Transport, Education, Healthcare). Each axis score is derived from multiple underlying statistics.
The "Q&A with Kai" section on each city page is editorial content prepared based on government statistical data. The interpretations and perspectives offered are for reference purposes only and should not be the sole basis for any relocation decisions.
